I tried this script, on all ports, 0 through 6. (7 is not valid)

--initialize Aux serial port to 115200, 8, N, 1
initSer&#40;4, 115200, 8, 0, 1&#41;

function onTick&#40;&#41;
 --read a line from the aux serial port with a 100ms timeout
 value = readSer&#40;4, 100&#41;
 if value ~= nil then
  println&#40;'read value&#58; ' ..value&#41;
 end
end

nothing happens it just sits there printing "read value: " with a blank. It's not a nil because the IF statement is true and the "read value:" prints. Except nothing prints. I tried all the ports. It's like the serial commands don't work with the RC Track 2.

Doing a bit of digging around, sounds like the readSer command is problematic and it's preferable to use the readCSer command. Sounds like what I'm experiencing is similar to this:

It's probably no coincidence that Brent's GoPro Lua script uses readCSer instead of readSer.

No response on any serial ports. I tried with/without the initSer command, tried 115200 and 921600 baud rates. Tried with all ports turned off, WiFi, Bluetooth, CAN, GPS.

Also tried sending the AT commands to the ESP8266 WiFi module. Still nothing.

Looks like the serial port commands via Lua don't work with the RCTrack2.

Code: Select all

setTickRate&#40;10&#41; --TickRate is in Hz
initSer&#40;0, 115200, 8, 0, 1&#41;
initSer&#40;1, 115200, 8, 0, 1&#41;
initSer&#40;2, 115200, 8, 0, 1&#41;
initSer&#40;3, 115200, 8, 0, 1&#41;
initSer&#40;4, 115200, 8, 0, 1&#41;
initSer&#40;5, 115200, 8, 0, 1&#41;
initSer&#40;6, 115200, 8, 0, 1&#41;


function onTick&#40;&#41;
port0 = readSer&#40;0,100&#41;
println&#40;"Port 0&#58; " ..port0&#41;
port1 = readSer&#40;1,100&#41;
println&#40;"Port 1&#58; " ..port1&#41;
port2 = readSer&#40;2,100&#41;
println&#40;"Port 2&#58; " ..port2&#41;
port3 = readSer&#40;3,100&#41;
println&#40;"Port 3&#58; " ..port3&#41;
port4 = readSer&#40;4,100&#41;
println&#40;"Port 4&#58; " ..port4&#41;
port5 = readSer&#40;5,100&#41;
println&#40;"Port 5&#58; " ..port5&#41;
port6 = readSer&#40;6,100&#41;
println&#40;"Port 6&#58; " ..port6&#41;

end
